ABSTRACT:
In a computer system having at least a main storage unit and a memory control unit, a storage control system accesses two memory areas provided in the main storage unit, each of the two memory areas storing the same information. A double-writing device is provided in the memory control unit for writing the same information to each of the two memory areas by determining the state of a double-writing bit (D-bit) contained in an address order from a processor or the state of a storage configuration bit (F/S-bit) sent from the processor.
